Chapter 3, Problem 55E

Interpretation Introduction

Interpretation:

The given table containing the units of energy in $\text{J}$,$\text{cal}$, $\text{Cal}$ and $\text{kWh}$ is to be completed by carrying out the conversions from one unit to another.

Concept introduction:

There are several units of energy. Joule is the SI unit of energy.

Joule, calorie, Cal and kilowatt hour are the units of energy.

The energy conversion factors are listed below:

$\text{1}\text{cal}\text{(calorie)}$	$=$	$4.184\text{J}$
$1\text{J}$	$=$	$\text{0}\text{.239}\text{cal}\text{(calorie)}$
$\text{1}\text{Cal}\text{(Calorie)}$	$=$	$\text{1000}\text{calories}$
$1\text{ Cal}$	$=$	$\text{4}\text{.184}\times {\text{10}}^3\text{}\text{ J}$
$\text{1 kWh}$	$=$	$\text{3}{\text{.60×10}}^{\text{6}}\text{J}$
